Production of butanol by an improved fermentation process |
(57) An improved process for the production of butanol by fermentation of carbon-containing
compounds with C. acetobutylicum is disclosed. The fermentation is conducted in an
aqueous medium containing a sufficient concentration of dissolved carbon monoxide
to give increased yields of butanol while suppressing the formation of hydrogen and
acetone. This fermentation also gives increased conversion of butyric acid to solvents.
